Advances in using nature inspired solutions for improving heat transfer enhancement and energy utilisations
Living things have been continued to evolve under the pressure of survival and show structures with certain functions. They provide inspirations for humans to cope with challenges that we face today. In this lecture, I aim to highlight what we could learn from nature to tackle the challenges in heat transfer and energy utilisations for improving the efficiency and sustainability, and to introduce our recent progresses of the work inspired by nature or biological entities.
Our previous focus on biomimetics was concerned with mimicking plants and animals’ surface morphological nature for possible solutions of flow drag reduction and heat transfer enhancement, and this still strongly draws our research attention to improving understanding of the mechanism and putting forward new applications, such as in nucleate boiling, spray cooling, and de-icing.
In terms of the recent research efforts and progresses, two works will be reported. One is applying the nature inspired solutions to energy transfer and storage involving using composite phase change materials with hierarchical porous structures for medium-high-temperature energy storage for solar energy applications. Such biomimetic structures, inspired by natural plants, help avoid the leakage of phase change materials in the porous and improve overall performance of heat transfer.
The other recent progress is concerned with the application of radiative cooling coating inspired by nature solutions to building for sustainable built environment. This work provides a novel strategy for designing, fabrication, and applications of high-performance radiative cooling materials.
